Hanging Positions from VW import via CSV

As a precursor to all of this, I should point out I'm incredibly new to Wyg, so you'll have to forgive the lack of knowledge I have.

The process of exporting instrument data form VW to CSV and then import ing to Wyg could not be simpler, which i am super grateful for. The part I am unable to figure out is the hanging position information. I can export the field for the hanging data and when I do the import, the fixtures have the correct position listed in their properties window, but every fixture comes in hung on its own individual 3' pipe.

Is there some way around this? On a related note, if there's no way around this, how do I drag multiple fixrtures to a hanging position? Right now when I select multiple fixtures and drag them to a new position, it only drags one of the selected fixtures.
